Linux / Unix: Bash Shell See All Exported Variables and Functions

How do I see a list of all exported variables and functions under Unix bash shell?

The export command makes your local variables global. The syntax is as follows:

 
export PATH=$PATH:/usr/local/bin:~/bin
export EDITOR=/usr/local/bin/vim
export SHELL=/bin/ksh
export LANG=En_US
export PAGER=/usr/local/bin/most
 

To make your local shell variables global automatically, export them in your ~/.profile or ~/.bash_profile file under Unix like operating systems. To see a list of all exported variables and functions pass the -p option to the export command:

 
export -p
export -p | grep  something
export -p | less
export -p | more
 

Sample outputs:

DISPLAY=unix:0
EDITOR=vim
HISTFILE=/home/vivek/.bash_history
HISTSIZE=1000
HOME=/home/vivek
LANG=En_IN
LOGNAME=vivek
MAIL=/usr/mail/vivek
MAILCHECK=0
PWD=/home/vivek
SHELL=/bin/bash
